Free-flight flutter tests in the transonic and low supersonic speed range of three low-aspect-ratio swept, tapered wings on rocket-propelled vehicles

William T Lauten, Burke R O'Kelly

Abstract

Report presenting flutter data obtained with the use of rocket-propelled vehicles in the transonic and low supersonic speed ranges for three low-aspect-ratio, highly tapered, swept wings. Structural influence coefficients were obtained for each of the three plan forms and calculated mode shapes and frequencies are provided. Time histories for each of the configurations also demonstrate the flutter pattern of each wing.
